盐度

During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

Under action of wind in same direction with flood and for the reason of surface stress, the whole salinity both in surface layer and bottom layer are increase a little, while, the practical cases in estuary are complicated, and the existence of wind may effect on the distributaries between groove and shoal, so exceptions will be natural.

较宽阔的外海区，其表层盐度增加，底层由于垂向风生环流的作用，也会出现盐度减小的情况。

The problem of plant's tolerance to salt is mainly the tolerance to NaCl. The research is mainly focused on two aspects: First, the study of salt-tolerance physiology in halophytes; second, the study of the injurious physiology in nonhalophytes. Thereby we can understand how to ameliorate or increase the plants'salt-resistance.

植物的耐盐问题，主要是指植物对NaCl的耐性问题，植物耐盐生理的研究，主要从两个方面入手：一是研究盐生植物对盐度的耐性生理；二是研究盐度对非盐生植物的盐害生理，从而了解改善和提高植物抗盐能力。

In the No.1 lode, the largest one in the area, the ore-forming temperature changes greatly from 160-400℃, and the salinity of the ore fluids also changes greatly (0%-9%) with appa-rent boiling phenomena while the smaller lodes are of higher temperature（280-400℃）and lower salinity.

规模最大的1号矿脉，成矿温度变化区间比较宽（160~400℃），流体的盐度变化范围也大（0%~9%），沸腾作用明显；而在规模较小的矿脉中，温度比较高（280~400℃），盐度比较低。

The results show that all of the oxygen consumption rates and ammonia excretion rates of juvenile turbots of the 6 groups have a slowly increasing trend, and the bigger extent salinity changed, the more distinct trend appeared.

结果表明：盐度改变后，各突变组大菱鲆幼鱼的耗氧率和排氨率都呈现出不同程度的逐渐升高的趋势，随着盐度突变范围的增大，变化趋势更为明显。

Effects of salinity on metabolism of juvinile turbotThe metabolism changes of juvinile turbots were determined when the salilnity changed abruptly from 34 tolow levels (28,23,18,12, 8ppt) and to a high level(40ppt).

盐度突变对大菱鲆幼鱼代谢的影响研究了大菱鲆幼鱼由盐度34向低盐(28、23、18、12、6ppt)以及向高盐(40ppt)适应过程中代谢率的变化。

The results show that Cu and Zn tend to be quasi-conservative, whereas Cd, Co and Ni are remobilized over a broad salinity range in the Changjiang Estuary.

结果显示，溶解态Cu和Zn在长江口低盐度区趋于部分混合保守性，其他三种微量金属都不同程度呈现出全盐度范围内的溶出行为。

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean.

海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

In the Weddell Sea Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water.

第三个可以变更盐度的过程与海洋第三个可以变更盐度的过程与海洋中冰的形成和融化有海水冻结时，溶于其中的物质被留了下来。

Chan and D.O. Shah, in which Klearfac AA-270 was used. OPP-n shwwed broadening effects for crude oil/ASP systems. OPP-10 can be conveniently used at high salinity, while OPP-4 used at ...

对克拉玛依原油／ASP复合体系，亦有展宽作用，OPP－10使界面张力向高盐度区单调下降，而OPP－4可使低张力区在较低盐度区展宽。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
